BPA and Your Child’s Sealants: What You Need to Know from Kelowna Dentists


Next to regular brushing, flossing and a little fluoride, sealants are an excellent way to protect your child’s teeth from cavities. Ever since Health Canada announced it’s considering banning bisphenol A (a sealant ingredient) in baby bottles, our Kelowna dental clinic has heard from a few parents wondering if their child’s sealants are safe.

The answer is yes. Yes, your child’s sealants, even if the materials contain BPA, are completely safe.

When media reports announced the government was recommending restrictions on the use of bisphenol A, the message to the public wasn’t as clear as it could have been: Restrictions are only in infant products such as baby bottles and formula cans. There are no restrictions on dental materials because products such as sealants are well within safety margins.

Why is BPA restricted in bottles but not the sealants in your child’s mouth? That’s a good question.

Baby bottles are often filled with formula that’s mixed with boiling water. At extremely high temperatures, bisphenol A is more likely to “leach out,” according to the Canadian Dental Association. That exposure to BPA is a little closer to the safety margins Health Canada has set, and infants have a higher sensitivity.

The sealants on your child’s teeth, however, are another matter. The human mouth won’t see the same kind of heat exposure as a baby bottle filled with boiling water. Plus, once those sealants are set, they quickly harden and stabilize.

That means there’s only a tiny bit of exposure which occurs within hours of the sealant placement before exposure reduces to almost nothing. When researchers looked into the BPA exposure from dental materials, they concluded it was so small, regulations just weren’t needed.

If your child is about to get sealants at your Kelowna dental clinic, you can expect your dentist to spend a few minutes telling you about the material being used before their treatment.

What other materials can be used for restorations in your child’s teeth? Our Kelowna dentists can offer a variety of materials, including stainless steel, gold, porcelain, resin and dental amalgam. Your dentist can help you decide which material is best for your child.
